The issues are nothing of anyone’s doing as far as I know, outside of maybe someone at the IRCd host, hehe…
The server went down for a short bit yesterday it looks like (March 21) – when it came back up, only SSL was working.

A support ticket to the IRCd host has been submitted, and we’re waiting on a response. In the meantime, you can connect using SSL on port 6697.

For mIRC, you can use the command: /server subdomain.domain.ext +6697
For other clients, please see their respective documentation.
